Which is an external variable influencing illness?

• A. Social support.
• B. Perceptions of symptoms.
• C. Type of illness.
• D. Attitude toward treatment.

Answer: (A)

External factors are elements outside the person that shape how illness is experienced and managed. Social support fits this because it comes from the person’s network—family, friends, and community—and provides emotional encouragement, practical help, and information. This outside support can influence when someone seeks care, how faithfully they follow treatment, and how effectively they cope with symptoms, all of which can alter the course of illness. In contrast, perceptions of symptoms are internal interpretations of what one feels; the type of illness is a biological condition; and attitude toward treatment reflects internal beliefs. So social support is the external variable that most clearly influences illness.
